The ground fork

The ground fork is used at parking exits
 for vehicles and places that prevent vehicle entry
 and the ground fork is made of sharp iron in the
 form of teeth that reach a height starting from 60 to 150 mm
 above the ground and with lengths sufficient to penetrate thicker
 tires.
• The ground fork can be placed in the ground or in the
 form of a speed bump and can be kept locked or open.
• The ground fork operates automatically as soon as a
 vehicle passes over it.
